Definitions
- the field of the present invention is model aircraft.
- Toys and models are currently available which perform as guided vertical lift craft such as helicopters and the like.
- Such devices have a body, are battery powered or engine driven and have a powered rotor system having one or more lift rotors. When two rotors are employed, they are advantageously counterrotating to eliminate yaw torque.
- Such devices range from simple toys to very sophisticated models.
- the controls associated with such devices also span a wide range from the simple to the sophisticated.
- Such devices can be controlled by wire but are more frequently controlled by an RF controller.
- the present invention is directed to vertical lift craft and the methods of their employment. Conventional and available such craft and controllers are contemplated to be employed in combination with cages enclosing at least the powered rotor system.
- flexible rods are arranged in an open mesh pattern with the rods being mutually attached at intersections therebetween. Netting extends between the flexible rods to cover the cage. The rods and netting are selected to prevent access to the powered lift rotor or rotors.
- flexible rods are arranged in an open mesh pattern with the rods being mutually attached at intersections therebetween. Netting extends between the flexible rods to cover the cage.
- the mesh pattern advantageously includes latitudinally and longitudinally extending flexible rods with elastomeric bumpers at the intersections between the flexible rods.
- a method for isolating a powered rotor system of a vertical lift craft includes creating a flexible cage, affixing netting to the flexible cage, limiting the power of the resulting craft such that it is limited to operating at speeds which do not result in the lift rotor or rotors engaging the flexible cage upon direct impact of the craft against the fixed barrier.
- a fourth separate aspect of the present invention includes a method for operating a vertical lift craft including creating a flexible cage about the powered rotor system, affixing netting to the flexible cage and operating the craft at speeds such that the powered rotor system will not engage the flexible cage upon direct impact of the vertical lift craft against a fixed barrier.
- the FIGURE is a perspective view of a vertical lift craft.
- a vertical lift craft is illustrated as including a body, a powered rotor system and a cage.
- the powered rotor system generally designated 12, includes two lift rotors 14, 16 which are counterrotating.
- the powered rotor system 12 includes a source of rotary power for the lift rotors 14, 16 which includes a battery 18, a motor (not shown) and gearing not shown) to achieve counterrotation of the lift rotors.
- the source of rotary power is located in a body 20.
- a mechanism (not shown) for controlling the direction of motion is also contemplated.
- This powered rotor system 12 is appropriately controlled by a remote controller using RF or flexible wire for communication with the system 12.
- Such powered rotor systems range from simple inexpensive toys to far more sophisticated models.
- One such source of the powered rotor system is Hirobo Unlimited of Hiroshima-Perfecture, Japan.
- the body 20, shown to be minimal in the FIGURE, may take on any reasonable shape to achieve desired aesthetics.
- the motor, transmission and battery for the powered rotor system 12 are simply fixed in the body 20 with the body 20 being substantially balanced about a vertical axis coincident with the rotational axis of the lift rotors 14, 16.
- the body is preferably of light construction with extensive use of foam.
- a cage is illustrated as extending about the powered rotor system 12 and the body 20. It is, however, contemplated that the body may include such things as wings or other aesthetic components, preferably of lightweight foam, which extend beyond the cage 22.
- the cage may be said to include a base defined by rigid struts 24 which are structurally fixed to the body 20.
- Axles 26, 28 rotatably mounting four wheels 30 are also attached to the rigid struts 24 of the base.
- the cage 22 is defined by flexible rods 32 of carbon fiber filled plastic to give appropriate strength with low weight.
- the flexible rods 32 are arranged in an open mesh pattern which, in the preferred embodiment, includes latitudinally extending rods 34 and longitudinally extending rods 36. These rods 34, 36 intersect one another and at least at a plurality of intersections, the rods 34, 36 are mutually attached together to form an appropriate rounded cage structure with substantial strength.
- Elastomeric bumpers 38 are provided at the mutual attachments between the latitudinally extending rods 34 and the longitudinally extending rods 36 at least about the equatorial line.
- the size of the cage and its strength may be defined so as to allow the craft at full speed to directly impact against a fixed barrier without distorting the cage 22 enough to interfere with the lift rotors 14, 16. This is accomplished through balancing the strength of the cage, the weight of the system and the limits of speed achievable by the craft 10.
- netting 40 extends between the flexible rods 32 which contemplates that any given piece of netting 40 may extend over several of the flexible rods 32.
- This netting 40 is of a very lightweight material with a very open pattern. Such material can be from conventional fabric stores.
- the cage 22 is affixed to the rigid struts 24 of the base to complete the structure.
